IMPROVEMENT IN LALPPING-MACHINES.

Specification forming part of Letters Patent N 0.' 199,379, datedJanuary 22, 1878; application filed May 26,1877.

in Lapping-Machines and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification, in which- Figure 1 is a transverse vertical section.Figs. 2 and 3 are side elevations. Fig. 4 is a rear view, partly insection. Fig. 5 is a transverse vertical section.

My invention consists in the peculiar construction and combination ofparts hereinafter described, constituting a machine for forming lappingfrom the web or sliver received from the carding-engine.

Referring to the accompanying drawing, A designates a cylinder or drum,which is arranged to turn loosely on a shaft, B, which has its bearingsin frames or arbors G G, constituting the sides of the machine. D D Dare feed-rollers, having journal-bearings in bars E E. The bars E E arepivoted at e e in brackets F F, sustained on the frames 0 O, and areformed with. lugs 6 fastened by screws 0 which pass through slots f inthe brackets F F. By this means the feed-rollers D D D may be adjustedrelatively to the drum .A.

G G are pressure-rollers, having bearings in the brackets F F. Saidrollers may be solid metal rollers, or they may be weighted or providedwith spring-bearings, which will press them toward the drum A, theirobject being to fold the web and compress the lap on said drum.

H represents the roller on which the lapping is wound, and I afriction-roller for causing said lapping to be wound not too loosely onthe roller H. K is an arbor, supporting a shaft, 70, which holds a fastpinion, k gearing with a wheel, k Said wheel W has a wristpin, k whichis connected, by a pitman, k, with a crank-arm, I), made fast on theshaft B.

By revolving the shaft 70 a rocking motion is communicated to the shaftB and to the brake'or dog. On the opposite ends of said arms the rollersH and I are sustained, the

journals of the former resting loosely in elongated slots-h h, while theshaft 2' of the latter is provided with a pulley, i and ratchet i 0 O PP are levers, articulated at 0 and '10,

being pivoted on the shaft 11 and on the screw Q, which is fastened inone of the adjustingholes 1" in the plate R, which forms part of or issecured to the side frame 0. The rocking action of the bars L L causesthe levers O 0' P P to be extended and contracted in the manner of alazy tongs, thus communicating, through the medium of the spring-pawls 0p, a continuous forward motion to the roller I.

S is a pulley fast on one of the heads of the drum A, and connected withthe pulley i by means of a chain, 8. Said chain conveys motion to thepulley S from the shaft '5, cansin g the cylinder or drum A to progressslightly forward at each oscillation or rocking communicated to it bythe arms L L, the frictionbrake N preventingsaid cylinder from passing,by momentum, beyond the distance which it is caused to move by the chain8.

The operation is substantially as follows: The web or sliver from thecard is received upon the feed-rollersD. D D, and falls upon thecylinder or drum A. The oscillating motion of the cylinder in onedirection carries said web (shown at T) under the roller G, by which itis lapped or doubled, as shown at t. The reverse oscillation of thecylinder A carries the folded material under the pressureroller G, wherethe formation of the lapping is perfected, the material passing thenceto the lap-roller H, on which it is wound. After each oscillation of thedrum A said drum is caused to make a slight advance toward the roller Hby means of the chain-connection s. The extent of the lap and motion ofthe cylinder A under the influence of the chain 8 is governed by theadjustment of the pin or screw Q in the plate R. The motioncommunic'ated to the roller I, by the means already described, beingcommunicated to the roller H by frictional contact, as shown plainly inFig. 5, gives the necessary rotation for wind ing purposes to saidroller H, and said contact also prevents the lapping from winding tooloosely. As soon as the roller H is filled with lapping it is lifted outof position, and another similar roller substituted for it. 7

By dispensing with one side or pair of the lazy-tongsleverssay,0l?-andretainingthe other side or pairsay, O Pthe motioncoinmunicated to the rollers H and I will be intermittent, the cylinderor drum A advancing on its axle under the influence of the chain 8correspondingly; but by retaining the two pairs of levers, as shown inthe drawing, the motion of said levers will be continuous, and the drumA will keep advancing or turning on its axle when oscillating in eitherdirection.

What I claim as my invention is' 1. The combination of the cylinder Aand mechanism, substantially as described, for 0scillating the same withthe rollers G G, substantially as shown and described.

2. The combination of the cylinder A and mechanism, substantially asdescribed, for oscillating the same, feed-rollers D D, andpressure-rollers G G, substantially as shown and described.

.3. In combination with the oscillating cylinder A, turning loosely onthe shaft B, the arms L L, fast on said shaft, and the friction brake ordog M N, substantially as shown and described.

4 In combination with the cylinder A, the winding-roller H,friction-roller I, and arms L L, substantially as shown and described.

5. The combination of cylinder A, loose on the shaft B, shaft 2',pulleys i and S, with chain 3, substantially as shown and described.

6. In combination with the roller I and mechanism, substantially asdescribed, for imparting a vibratory motion to the same, the shaft i,sustaining the ratchet V, the levers O P, and pawl 0, substantially asshown and described.

7. In combination with the roller I, mechanism for vibrating same, shafti, and ratchet t the lazy-tong levers O P, and pawl 0, the

adjusting-plate R, substantially as shown an described. I

In testimony that I claim the foregoing I have hereunto set my hand this16th day of April, 1877.
